We report 10 carcinomas in 8 patients with regional enteritis. Five of the cancers were in the ileum, 4 in the right colon, and 1 in the rectum. The visualized small bowel cancers appeared as benign strictures in small bowel involved by regional enteritis. Most were poorly differentiated. The colon cancers had a more typical radiographic appearance of malignancy. In some patients with small bowel cancer the malignancy was discovered only on histologic evaluation; the malignant nature of the lesion was not appreciated by radiography or gross examination at surgery. 相似文献

The speed of the last two types falls off considerably at lower kVp levels. 相似文献
